I lost an entire YouTube channel once. "TOS violation" was the only explanation given. No recovery option. It was almost entirely me playing instruments. No idea what the problem was. Absolutely no idea why they obliterated the whole channel. Surely not every video of me playing piano managed to violate the TOS. I wish there was a way to hold them accountable, but they're far too gargantuan.
I'd guess if he streamed on Youtube, his account is terminated so that's no longer possible.
I kind of want to go through the legwork of reuploading most of the 1100 videos and then giving Terry the username+password of the new channel. But I don't know if that will run afoul of Youtube's policies and I don't want to be banned for life myself.
(Archive.org snagged most of the 1100 videos, not just ~300. But some of them are just missing.)
Aw, Terry's YouTube channel was taken down. He did so many walkthroughs of HolyC and his dynamic programming engine.
Oh well, 353 videos were archived at least.
Thank goodness for archive.org!
